ATTACHMENT FOR DISK CUTTERS.

Specification of Letters Patent.

Patented June 23, 1914.

Application filed December 3, 1913. Serial N 0. 804,447.

To all whom it may concern:

Be it known that I, ELBERT CORY, a citizen of the United States,residing at Colfax, in the county of Clinton and State of Indiana, haveinvented new and useful Improvements in Attachments for Disk Cutters, ofwhich the following is a specification.

The invention is primarily designed to provide an attachment for use inconnection with a rotary or disk cutter for turning stubble, stalks,trash and the like under the ground so as to prevent interference ofsuch matter with subsequent operations.

The invention provides a blade and supporting means for holding theblade at one side of the disk cutter in position for turning the earthin such a manner as to cover stubble, trash or the like, said bladebeing adjustable to any desired position.

The invention consists of the novel features, details of constructionand combination of parts, which hereinafter will be more particularlyset forth, illustrated in the accompanying drawing, and pointed out inthe appended claim.

Referring to the drawing forming a part of the specification, Figure 1is a side view of a disk cutter provided with a turning attachmentembodying the invention. Fig. 2 is a top plan view. Fig. 3 is a sectionon the line a:a2 of Fig. 2. Fig. 1 is a detail perspective view of theattachment.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawing, by the samereference characters.

The numeral 1 designates a disk cutter of any type or design, the samebeing mounted upon an axle 2 which is held at its ends in the members ofa fork 3 which is adapted to be connected to a standard 4 of anagricultural implement of any variety. The fork 3 and disk cutter 1 areof ordinary construction and are illustrated simply to demonstrate theapplication of the invention which consists-of a shovel or turningattachment. The attachment embodies a beam 5 which is arranged alongside one of the members of the fork 3, the same having its rear portionturned as indicated at 6 and bent to provide a substantially uprightstem 7 The front portion of the beam 5 is curved upwardly at 8 and bentlaterally to provide a clip 9 which extends over a member of the forkand along the inner side thereof, the inner member 9 being bent inwardlyso as to overlap the upper flange of the fork member. A set screw isfitted into an opening formed in the upwardly curved part 8 and isadapted to engage the fork member at a point below the flange 12 so asto act jointly with the member 10 to prevent vertical displacement ofthe clip. The fork members are usually of T-form in cross section,opposite portions of the horizontal flange being engaged by means of theset screw 11 and clip member 10 in the manner herein stated. The beam 5is formed intermediate of its ends with an opening 13 which receives aprojecting end of the axle 2, the beam being retained in place by a nut14 threaded upon the outer end of the axle.

A blade 15 is secured to the stem 7 of the beam and is adjustablevertically and angularly. The blade 15 has a socket 16 upon its rearside through which the stem 7 passes, a set screw 17 threaded into anopening of such socket serving to secure the blade in an adjustedposition. The blade 15 approxr mates the form of a turning plow andcomprises a share and mold board, the parts being of such arrangement asto effect a turning of the earth at one side of the disk cutter. Theinner edge of the blade is arranged adjacent the proximal side of thedisk cutter so that in the operation of the device a slice of earth isturned at one side of the cutter thereby forming a furrow in which thematter such as stubble, stalks, trash and the like is covered.

It will be understood from the foregoing taken in connection with theaccompanying drawings that the invention provides a device partaking ofthe nature of an attachment to be applied to a rotary or disk cutter forturning stubble, trash and the like, thereby leaving the surface of theground free from such matter and whereby the latter is prevented frominterfering with the subsequent operation of implements such as harrows,or cultivators, or planting or fertilizing machines.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described theprinciple of operation of the invention, together with the device whichI now consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when desired as are Within the scope of the claimappended hereto.

Having thus described the invention, What I claim as new, is H Incombination, a fork, an axle supported in the fork members and having aprojectf ing end, a disk cutter mounted upon the axle,;

a beam mounted upon the projecting end of 1 the axle and havmg itsrearportlon bent" to 2 provide an upright stem and having its frontportioncurved upWardTy thence Tater- Copies or this patent may beobtained for five cents 1 ally to provide a 0H for embracing oppo sitesides of amem er of the fork, a set screw mounted in a member of theclip and i adapted to engage the fork member to hold the beam in placeand a turning plow adjnstably mounted upon the upright portion at therear ofthebeam.

testimony whereof I afiiX my signature in presence of tWo Witnesses. HELBERT CORY.
